Question and options

The lowest energy of a quantum mechanical harmonic oscillator is hν/2h\nu/2. It is referred to as
  1. Activation energy
  2. Zero point energy
  3. Vibrational energy
  4. Ionization energy

Answer and explanation

Correct answer: B - Zero point energy
E0=hν/2E_0 = h\nu/2 is the zero point energy: the energy the oscillator retains even at absolute zero. Activation energy and ionization energy are unrelated concepts, and 'vibrational energy' is a general term rather than the name of this lowest level.
